The Foggy Cityscapes-DBF [1]} dataset has the corresponding clear images with bounding box and segmentation masks. We strictly follow [2]} to synthesize more kinds of haze density images. Specifically, we set nine kinds of \(\beta \) , where the value of \(\beta \)  ranges from 0.004 to 0.02, and the interval is 0.002. Notably, it contains \(2975 \times 9\)  image pairs for training. Meanwhile, we evaluate on \(500\times 9\)  image pairs.
